APPARATUS FOR FBEEZING LIQUIDE.

Application :tiled December 8, 1914.

To all whom it may concern:

lie it known that l.y HENRY l?. ROBERTS, a citizen of the United States,und a resident of Roxbury. county of Suffolk, State of Massachusetts,have invented an Improve nient in Apparatus for Freezing Liquids, ofwhich the following description, in connection with the ziceonipanyingdrawing` is a specification, like. characters on the drewing renesentinglike parts.

This invention relates to :minuntos ior reering liquids und nertninsmore particularly' to irre/erf: 1Cor making ice cre-1m and the like,

ln the accompanying drawing and the herein description of the inventionI disclose but e single embodiment herein in which,

Figure 1, is a central vertical section through the longitudinal exis ofsin ernhodnnent. Fig. 2 is a central vertical sec- Fig. 3 is a pertionon line Q of Fig. 1,.

the chilling spor-,taria new et en zlsfitntor lor receptacle.

rl he iL-#lne employed herein. are used in the nene ud descriptive senseto disclose the :t-1m., nid single embodimentend therefore me not orinierily words of limitation of this in v ei di on.

In the drawing 1() represents ey buse provided with :i trough likeportion. pair ol standen-ds 12 having at the top there of bearings 13.'Between seid standards I preferably provide l e container 15 havingshafts 16 adapted to rotate in the aforesaid bearings 13. One of saidshafts is provided with a crank 17 or any other suitable means forimparting rotary swinging or oscillatory motions to the container 15.For convenience the said container may be provided with an orifice 18normally closed by the cover 19 screwed or otherwise .fastened to thebody of the container. Herein for exemple, the said cover and containerare provided with screw threaded portionsfl) land 21 respectivelypermitting the Irernovel of; said cover for the {iurpose here nafter setforth. Another portion of the seid coni tainer 15 is provided with nscrew threaded flange 22 and engages .a similarly screw threaded flange24 on one end of a receptacle Q5 adapted to receive therein chilled orfrozen and when in operative p0- sition is surrounded by the saidcontainer 15.

As herein shown the said container 15 and l have illustruterfl ll and n.

the two nre in operative relation thc lornier surrounds the hitter withan interveningr space 21'. That is the said rontniner is oil' largerdiameter than. the receptacle und the lutter projects within thefoi-nier thereby providingr a closed rhuniber within which is placed thefreezing or chilling agent,

A pair of logs 2H project from the llnnge 124 to enable the operator tomore firmly ifrnsp the snid flange for the purpose ofV rototingr it andthe receptacle so that the re= ceptncle may be Withdrmvn from theinterior of this .container 15. The said flange when screwed to thecontainer l5 holds the re ceptncle 5 in operative position Within theformer. A. flanged cover 3o is screw threaded nt 31 to the end of thereceptacle 25 to prevent leakage ot the liquid from the receptacle whenthe latter being rotated or otherwise moved.

lVithin the receptacle i provide un agitator or plunger 35 separate fromand. entirely independent et any ot the parts herein described Thisplunger il@ muy be of any desired or preferred form or configurationmoet suitable for the purposes ci e plunger to reciprocate relative whenlocated therein.

This rihhedconstruction or similar` ,construction therefore vpresents circularrolling und scraping edges adapted to agitato the liquid to be frozenand to rethe accumulations of tlre liquid frozen move to the interiorsurface of the receptacle 2.5. The sectors formed' by the intersectingdisks or ribs are provided with holes which assist the process ofagitation of the liquides the said plunger by its combined sliding androlling motions moves from end to end o said receptacle.

Having described tne structure ot me were ent embodiment of my inventionthe opera tion thereof is as follows: The cover 19 is removed from thecontainer and ice and salt or any other sui able chilling agent is ackedin the space' 26 about the receptacle 2 until said space is fairly butnot completely illedA the said cover 1s sorewedbaek the llange 40 snuglyengages The container is then rotated 30 is uppermost; The cover afterwhich in place until the container, ,so that'the/cover to the rrwptecleand f loo
